UNirsDfs'rATss SPOOL Waiter-R. West, nightstown, N. J., assigner to` 4Hightstown Rug Company, Hightstown, N. J., corporation of Delaware Application June 29, 193s.l serial Ne. cisnes claims. (o1. aref-124i My invention 'is particularly applicable to spools for holding. warp. yarns in` ,Axminster looms and of the type lin which the .core of the spool is formed of wood and the end flanges on 5 the core are formed of metal disks each having a metal trunnion,u;formed by ya gudgconi-in coaxial relation with the core and extending into` y the latter; one of said gudgeons being cylindrical and fitted to be journaled in a bearing in 1o the loom, and the other having means., such as a diametrical flange or slot, to be rotatably .engaged by means for controlling the rotary move ment of the spool. Ordinarily, such a spool core has a groove in its circumference extendvl5 ing from end toendthereo parallel with its axis in registry with :holes in the .end disks, so

' that when the ends of the yarn are wrapped in Ya single convolution around the core, "said ends may be secured in position by a rod extending f2() over them in said groove -and engaged in the holes in said disks at the oppositeends thereof.

.Ordinarily, the end disks are primarily fixed in` coaxial relation with the core by spikes on` the (disks which are driven into the Wood at Ythe ends of the core. However, the relative torsional vstresses to which the end disks and their connecting cores are subjected ultimately twist the disks on the cores and split the latter with the c Therefore, it is the object and effect of my linvention to provide means for engaging the end .f disksivith the cores Vin addition to the spikes aforesaid ,and capable of engaging the-:core to ting under such relative torque stresses. As hereinafter described, the essential feature of @my invention is the provision of metal keys of channel form, fitted in the .opposite ends of the grooves in the cores, and lprojecting into thel openings in the end disks, and Ameans, for detacha'oly permanently securing such keys in proper engagement with the cores and disks.

My invention includes the various novel feav tures of construction and arrangement hereinafter more deiinitely specied.

the wooden core -In said gures, thespool core 1 has the. groove 60 2 in the circumference thereof extending parallel withits axis throughout its length. Said' core is `provided with circumferential flangesat its oppositeendsbythe respective disks 3 vand 3', which differ only in that the latter `has a cylindrical flange at its perimeter, but are alike in that they each have spikes 4 projecting inwardly therefrom into 'engagement with the ends of the corey 1; said spikes being conveniently formed in unitary relation with the respective disks 3 70 by metal punched from thetriangular openings 6 in said disks. Each of said disks hasv apartly rectangular opening '7 thus held in registryrfwithv y the respectivelyopposite ends of Vsaid groove 2 and withan arcuate notch in', thesouter yedge of 7'5 said opening` 7 adapted to receivethe opposite ends of the rod 8 which are detachably fitted in said grooveas aforesaid;

Each of the keys 10 is of channel form', as indicated, tted in, opposite ends of' the groove 2 80 in Said COT@ 1; @ach having at its outer end ange 11 extending radially inward in `column;

with the outer face of the respective disk 3 and having a circular opening"12 therethrough in coaxial relation with the opening"13 in the'disk 35 to `receive the respective 'shanks' l5 of the gudgeons 16 and 17, each of which is cylindri- .caland has at itsinner end a reduced screw threaded portion 18 `for engagement with respective nuts19 whichare ntted inradialjopen- 9o ings 20 in said core. f

Said gudgeon ,16 has the cylindrical head 22 bearing against the Vouter surface of the flange 11 and provided with diametrical slots `2 3 in` crossed relation to receive any suitable driving meansfor turning the vspool. The double lines at-the edges of saidslots 23 in Fig., II merely 4indicate that said Yedges are chamferedas indicated in Fig. I, to facilitate the insertion of the driving means therein. The gudgeon 17 has 100 a head 25 with a'cylindricalA trunnion 28 thereon to be journaledin a suitable bearing in the loom frame. 1 A i It is to be understood that the relative torsional stresses between the end disks 3 of the 105V spools and their cores l are dissipated throughout the length of said keys 10 so that rupture of the spool ends by twisting movement of the spikes 4 isv avoided. y

However, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my inven- Y tion, as defined in the Vappended claims.
